This invention relatesto sorting and binding desks and is designedfor the manipulation, sorting and binding ofp'apers which are tofbe perforated and bound for filing and other purposes.

With the above and other objects in view, as will be apparent, this invention consists in the construction,combination and arran ement of parts, allras hereinafter more full? described, claimed and illustrated in the accompanying drawing wherein:

This compartment 12 is of a size sufiic'ientto receive a flatoihor zontal position the largest sheet is des red to bind andof ,adepth sufficient to entirely contain the largest 'bund'le of papers it is desired to create. i 4 Q f V The bottom 13015 the compartment l2 is flat and occupies a plane parallel to the plane of the sorting surface :11 of the desk ll]. Along its forward ede the bottom a! slot 14 which, as wil be hereinafter moi-[Q fully described, permits ot the ,hin'ding or fastening of tlie huiidle while it is stillin the compartmentjlZ. v a

At its side, corresponding to the'front edge of the sorting surface 11, the compartment 12is open and is thereprovided with aIgTatc 15 adapted to swingfon theflhingesi1 6 be 15 3,7115 Pics;

tween one end of the gate and the vfront end p of one of the side walls 19 "of the compare ment. The free ends of the gate l5 liasa latch or bolt or other fastenin means 1:? mounted, thereon ior cooperation with a tie sleeve or ,otherengaging means 18 at or ad oining the forward end of the remaining a side wall 19 of the compartment. 12 m lock the said gate in a closed position; (Fig-r ureQ). v The side walls'19 of the compartment l2 are each provided with a series ofgrooves 20 for the receptionofthetop pressureplate 21; The opposed grooves 20 of the side walls 19 are coplanar'so that the top pressure plate 21 whenfins'erted in a pair thereof, occupies a position substantially parallel Ito the bottom 13of the compartment 12. As the grooves 20 extend to and through the front ends-of the side "walls 19 of the compartment 12, the top pressure plate 21 may be inserted in any two'opposed coplanar grooves, when the gate 15 is open After the papers have been sorted or classi IOU x it fied on the sorting surface 11,eacl1 pile, group or class isplaced in the binding compartment 12 with the edges to be bound at the front thereof. When the gate 15 is closed the edges to bebound of the papers are placed or bear againstthe gate, which acts as a guide and abutment therefor. If the papers are of less dimensions than those of the compartment 12,0ne of the sides at right angles to the edges tobe bound may be placed against the adj oining one of the side walls 19 of the compartment 1 2 which {likewise acts as a guide or abutment therefor. Thus after the gate 15 is closed, the papers placed in the compartment 12 are positione'dfby the gate 15 and Walls 14 1 so that at least two of the edges of each sheet rest in the same, or approximately the same vertical plane as thecorresponding edges of the remaining sheets contained in the compartment. A pile or group of sheets or papersof' less dimensions than those of the compartment 12 are indicated at 22 (Figures 2, 4: and 5): In the event the papers or sheets are of the same dimensions as the compart ment 12, the edges thereof bear against both side walls'19,]the gate 15 as well as the rear wallof the compartment, but in every case the edges to be bound should bear against the gatel5. 1

, Subsequent to arranging the sheets and papersas aforesaid,'they are compressed as much aspossible and held in this condition until the gate 15 isopened and the top. pressure plate 21 inserted in the grooves that will most nearly position the plate 21 tightly against the top of the pile, such as 22, as shown. In. this manner the stack of sheets 22 in the compartment 12 are held compressed by the plate 21 forperforating and binding.

In the binding stack or pile of sheets not already punched, such as that'shown at 22, it isnecessa'ry to perforate thesheets at predetermined intervalsadjoining the edges to be bound, for the reception ofthe binding orfasteningineans such as laces, pins orthe like. The perforations have in past been formed in the papers by means of an electric drill'and it isthe purpose of the present invention to cooperate with such drill by providing a guide for the same and todetermine the location ofthe perforations'whereby the holes created will be straight and properly positioned. 1 o

For this purpose the top pressure plate 21 isprovided'with a slot 23 adjoining the outer edge thereof, which when the pressure plate is positioned in the'grooves 20 so that the rear end thereof isat the terminals ofthe groove,

said slot23 will be aligned verticallywith theslot 14 in the bottom 13 of'the compartmentf12. This slot at predetermined intervals merges into enlargements 24 which correspondto the shape but are somewhat larger thanthe drill usedto perforate the stack or pile of sheets 22 These enlargements corlargemcnts 24 and'25;

a through,

respond to similar enlargements 25 formed in the slot 14 of the bottoin13 of the compart ment 12 so that the drill will in its operation through the sheets pass through both the en Cooperating with the pressure plate 21 is a guide 26 which constitutes a block cooperating with'the plate and having a slot 27 registering and co-extensive with the slot 23 of the plate 21. This slot 27 of the guide 26 is provided with a series of enlargements 28 which are so spaced that they register with the similar enlargements 24 of the plate 21. These enlargen' ents 28 however are of a rcaterdiameter than the diameter of the rill used for the reception of the guiding bushings 29 which are inserted therein and each of which has a passage 30therethrough, of a diameter substantially equal to the diameterof the drill used. These bushin s are removable from the guide 26 and may e and are inserted in the enlargements 28 through which the drill is to be passed during the perforation of the papers. f

In practice, after the papers have been clamped as illustrated at 22in Fi ures 2, 4 and 5, theelectric drill is inserted into the passages 30 of the bushings situated adjoinmg and over the bundle of paper thereby drilling a hole through the papers under the ill! budge or bend in passing through the papers and will drill a straightaperturethereand by haw'ngthe enlargements 25 in the slot 14 the drill after passing through the sheets will enter the same rather than imping ng onthe bottom 13 to be broken therey- When the papers have been punched before being received for arranging and binding, the perforating operations referred to herernbefore are not necessary but the papers are arranged in the compartment manner as if for perforation.

After thepapers have been arranged and the operations performedas aforesaid, and while the papers are held compressed b the plate 21, the fastening means such as aces, pins or the like are inserted therein, the slots 14 and 23 and the enlargements 25 and 24 thereof are sufficiently large to permit astening meansto pass therethrough and engage and secure the papers. When this is done the plate 21' is removed andthebundle is readyto be filed. Q p t Inthe form of the invention shownin Figure 7, theguide 26" having the slot 27, and the enlargements 28 is carried bythe gate17 so that after-the pressure plate 21 which in this instance does not carry a guide261is in place, the gate may beiclosed and the guide 26 may be used during creation of the per forations inithe paper. 2

It will be observed from Figure 4that one 1. In abinding machine for paper or other sheets, a receiver having a bottom and side walls, the said bottom having a slotformed therein adjacent itsfront edge, the said side walls having grooves formed therein and extending along a portion thereof toan abut-- ment, and a pressure plate having a slot therein adjacent one edge'thereof, the said plate arranged to be receivedby the said grooves and to engage the said abutment so that its slot will register with that in the bottom of the receiver.
